MAX4651EUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4651EUE+ is a low-voltage, quad single-pole single-throw (SPST) CMOS analog switch housed in a 16-pin TSSOP package. It features four normally closed switches with a maximum on-resistance of 7Ω at +3V and 4Ω at +5V. The device operates from a single supply voltage ranging from +1.8V to +5.5V. Key electrical parameters include an off-leakage current of 0.1nA at +25°C, a turn-on time of 20ns typical, and a turn-off time of 12ns typical. It supports rail-to-rail analog signal processing and maintains on-resistance matching within 0.2Ω.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the marking code against official Maxim Integrated documentation. Confirm the suffix 'E' indicates the industrial temperature range (-40°C to +85°C) and 'U' denotes the TSSOP package. Ensure the '+' suffix confirms compliance with RoHS standards as per the manufacturer's ordering information.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4651EUE+ when a normally closed configuration is required for the analog switches. Compare it against the MAX4652 for normally open requirements or the MAX4653 for mixed configurations. Consider the 16-pin TSSOP footprint constraints and verify that the +1.8V to +5.5V supply range aligns with the system design.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4651 belongs to the MAX4651/MAX4652/MAX4653 family of low-voltage, 4Ω quad SPST CMOS analog switches. These devices are designed to replace mechanical relays in automated test equipment and applications where current switching is necessary. They offer reduced board space and higher reliability compared to electromechanical alternatives.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional equivalents within the same package include the MAX4652EUE+ (normally open) and MAX4653EUE+ (mixed NO/NC). For pin-compatible replacements with different switch states, verify the specific application requirements regarding default switch positions before substitution.
